Web application security firms HP (SPI Dynamics) and Cenzic have called off the dogs in a patent dispute over fault injection technology.

The two companies had sued -- and countersued -- each other over the use of fault injection in Web application security scanner but, in a brief statement today, HP and Cenzic agreed to dismiss the lawsuits and enter into cross-licensing deals.

The Hewlett-Packard Company (HPQ) and Cenzic Inc. have signed a settlement and cross-license agreement for the patents HP and Cenzic are currently asserting against one another. This agreement settles the outstanding litigations filed by SPI Dynamics (which was acquired by HP) in Federal Court in Georgia and filed by Cenzic in Federal Court in Virginia, and these lawsuits will be immediately dismissed.
